Be on guard for yourselves and for all the flock, among which the Holy Spirit has made you overseers, to shepherd the church of God which He purchased with His own blood. I know that after my departure savage wolves will come in among you, not sparing the flock; and from among your own selves men will arise, speaking perverse things, to draw away the disciples after them. Therefore be on the alert, remembering that night and day for a period of three years I did not cease to admonish each one with tears. Acts 20:28–31, NASB
True, genuine, authentic Christianity is exclusive. It is not a smorgasbord or buffet of options from which men may take what they like while rejecting the rest and still call themselves Christians. While a statement like that may not be popular in this postmodern, politically correct, 21st century culture which advocates tolerance that is sort of a give and take “conversation” in which people with opposing views find a middle ground, it is still the truth. Authentic Christianity is quite the opposite. That is not to say that many who call themselves Christians have not colored their own personal theology with postmodern presuppositions, but these are what we call apostates. What is that?
